5.1.2.4 Points for attention

If you only want to check whether the VFD runs properly, set P90.00=0 (Common application
mode). When you perform the test without connecting to a motor, to make the output frequency
equal the set frequency, set P00.00=2 (Space voltage vector control mode).

If you perform empty-load commissioning, set P90.00 to 1 (Lifting in open-loop vector control),
set P11.08 to 0x000 (to shield the underload protection function), and set P90.14 and P90.15 to 0
to prevent the torque verification fault reporting caused by empty load. In addition, if no external
braking resistor is connected, you need to increase the ACC/DEC time to prevent the bus
overvoltage fault reporting caused by too fast stop.

If there is a brake feedback signal, set P25.02 to 75, and the macro has set this parameter by
default. In addition, set P90.31 to 1. If there is no brake feedback signal, set P90.31 to 0 to
prevent the misreporting of a brake feedback fault.

During onsite commissioning, if the VFD terminal signal upward/downward running command is
inconsistent with the load lifting/lowering direction, adjust any two phase sequences of VFD
output terminals U, V, and W.

If PLC control is used, speed signal and other input and output signal functions need to be
adjusted according to the actual control logic.

This macro can meet the requirements of most lifting application cases, and the performance
parameters have been optimized and do not need to be adjusted in most cases. If an exception
occurs, see the function parameter chapter for adjustment or contact the technical support.
5.1.2.5 Macro parameters (P90.00=1)
According to the closed-loop vector control parameter table, you can switch to the open loop vector
control by modifying the following parameters or setting P90.00=1.
